Enhanced microscale heat transfer phenomena in macro geometry

Abstract

Microchannel heat transfer receives huge interest due to its wide range of applications, since it was first introduced by Tuckerman and Pease [1] in 1981. The high heat removal capability of microchannel heat sink meets the demand of high heat dissipation from various applications, especially in the microprocessor industry. However, there is little agreement between researchers as to whether conventional theories can be applied to predict fluid flow and heat transfer phenomena in microchannel. Some researchers have reported general agreement, while others have reported discrepancies from the conventional theories. Additionally, most microchannels’ fabrications require advanced manufacturing technologies, which impose constraints on the development of microchannel heat sink. Hence, the aim of this final year project is to analyse microchannel heat transfer in macro geometry which can be manufactured through conventional manufacturing method.
